Thank you, Andrew, and John. Thank you, address@hidden for your codes :-)
Doing interpolation first is a reasonable and straightforward
solution, of course. Actually, what I want is something like the
SPTNQ and DPTNQ functions in ESSL library. In other words, I just
wonder if there are some methods to extract the weights generation
functions in GSL according to the desired quadrature algorithm, so
that I can do w[0] * f(x[0]) + ... + w[n - 1] * f(x[n - 1]) directly.
